Why is this in our collection?

Composed of a curved tubular metal stand, a plastic wheel, and cards, this file for storing names, addresses, and phone numbers is an artifact of the pre-digital office. Turning the wheel flips the cards, creating multiple planes. Some electronic versions are designed to evoke the tactile qualities of the rotating wheel.
